Nah, use whats on the board and add any if needed. Just place the needle on a bit of flux so it will melt and u dont burn the board or any neighboring components.
Try to keep the amount of solder the same as the other wires like it, depending on the circuit, it could cause more power to be drawn through the larger amount of solder; changing how the circuit acts. Chances are, it doesnt matter in this instance, but i couldnt tell u without seeing the circuit board.
